1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Inflammatory Myopathies (IM) encompass a diverse group of systemic autoimmune muscle disorders, not easy to diagnose. Concentric-macro EMG is supposed to reflect electrical activity of the entire motor unit. It could help in electrophysiological characterization of inflammatory myopathies and recognizing earlier myopathic changes. Conventional EMG in our IM patients showed myopathic changes in all the cases, so it could be a golden tool for diagnosis. The degree of abnormalities was variable in different muscles in concentric macro EMG. Myopathic changes using concentric macro EMG was not so advanced as those seen in chronic stable relapsing phase. Pooling up the results of the conventional EMG, muscle enzyme tests, muscle ultrasound , and Con-Mac will give optimal results for diagnosis and could help in follow up of patients with IM.
